Purpose:
AOAC SMPRs describe the minimum recommended performance characteristics
8
to be used during the evaluation of a method. The evaluation may be an on-site
9
verification, a single-laboratory validation, or a multi-site collaborative study. SMPRs are
10
written and adopted by AOAC Stakeholder Panels composed of representatives from the
11
industry, regulatory organizations, contract laboratories, test kit manufacturers, and
12
academic institutions. AOAC SMPRs are used by AOAC Expert Review Panels in their
13
evaluation of validation study data for method being considered for
Performance Tested
